Abstract

The most potential biomass to be developed with a high lignocellulose content is wood.  Calorific value estimation based on the results of biomass analysis such as the proximate test can be used as an alternative to predict the calorific value accurately, quickly, and economically. Therefore, in this study, it is important to measure the calorific value simply using the proximate method with an analytical approach to the chemical content of the raw material. This study used three species of wood consisting of jabon (Anthocephalus cadamba Miq), ulin (Eusideroxylon zwageri), and api- api (Apicennia sp.). This study's chemical components that eximined in this study consist of extractive, holoselulose, and lignin content. The proximate analysis consists of volatile matter content, ash content, fixed carbon, and calorific value. The results show that ulin wood has the highest calorific value (20.13 MJ/kg), then api-api wood and last jabon wood. The high amount of calorific value is contributed by the high value of lignin, extractive, and fixed carbon.

Abstract

Nowadays, there is growing interested in development of environmentally friendly and nontoxic wood adhesives. The objective of this research was to determined the characteristics of starch, tannin, and cowhide adhesives by adding phenol formaldehyde as a fortifier. The quality of its bonding properties for afrika laminated wood was also investigated.  Determination of characterization of bioadhesive was conducted based on SNI 06-4567-1998. The quality of bonding properties for laminated wood was conducted based on SNI 06-6049-1991 and all parameters values compare to JAS 1152-2007. Based on the research characteristic of bioadhesive values for visualization tes, viscosity tes fullfill SNI 06-4567-1998 requirement. For pH, solid content, and glatination time not all sampel fullfill requirement values. All parameters of physical properties of all of sample afrika laminated wood meet the JSA 1152-2007 requirement. For Afrika laminated wood made from starch and tannin adhesive have good value for delamination test. Moreover, for shear strength parameter test not fullfill JSA 1152-2007 requirement. All of sampel have only for interior purposes.
